    DIFFERENT DEGREES OF WATER PIPELINES LEAKAGE MODEL ANANYSIS AND GPR SIGNAL FORWARD SIMULATION

    • Application of ground penetrating radar on underground pipeline detection has been widely used in municipal engineering, However, the use of ground penetrating radar to detect underground pipeline leak has not yet been widely adopted in China. This Paper investigates the application of GPR in detecting urban water supply pipeline leakage. Firstly the seepage law of pipeline leakage area under different conditions were simulated by Geo-studio seepage Software, the geometric and physical parameters of the leakage area under different line sizes, different leakage sites and different times are analyzed. On this premise, using simulation software GprMax to study the radar geological image simulating of pipeline leakage under different conditions. It provides the basis parametric data and identification information for the actual use of ground penetrating radar in detect water supply pipeline leakage.
